Derivative of a function using the Quotient Rule

In this video, I showed how to use the Quotient Rule for taking the derivative of a rational function

[holyshit]

sqrt(1+sin(x))y = cos(x)
sqrt(1+sin(x))= cos(x)/y
y' = -1/2 cos(x)/y
and we have separable differential equation
y'+tan(x)y = -1/2sec(x)y^3
Bernoulli differential equation
Your function is particular solution of these differential equations

I hope you don’t forget me when you eventually do reach 250k :)
